Intel 80286 CPU Errata: ARPL
|
|
---
|
|
|
|
[The following information is from an Intel document titled "80286 ARPL and Overlength Instructions, 15 October 1984"]
|
|
|
|
### ARPL (63H)
|
|
|
|
When the second operand of the ARPL instruction (as described in the iAPX286 Programmer's Reference Manual) is a null
|
|
selector, the ARPL instruction generates exception 13. This behavior of the ARPL instruction has not been previously described,
|
|
but will be described in future revisions of the "iAPX286 Programmer's Reference Manual."
|
|
|
|
This functionality of the ARPL is not believed not to be a problem, and there are no plans to change this functionality
|
|
of the ARPL instruction.
